It was balmy outside. The aspen trees in the backyard oasis danced and glimmered in the warm summer breeze. The soft hum of bumble bees in a nearby bush was barely discernible over the slow rustling leaves and the air was thick with a sweet garden scent. Natalie, thoroughly convinced that all her housemates were gone and that she was alone for the weekend, lay naked on a soft towel in the grass, drifting in and out of a lazy mid-day nap. She lied there for nearly an hour, just letting the sun caress her with his warmth, licking his way over her smooth, silky body. She stretched luxuriously onto her towel and spread her legs towards the sun's deliciously warm waves.
Slowly, she became aware of the stirring in her groin. The encompassing heat of the sun on her privates was beginning to arouse the young woman. She grinned, noticing the small flutters of excitement throbbing their way through her vaginal walls. She touched herself. Slowly, at first, playing with her clitoris, pinching it between her thumb and forefinger. And then faster, as she slid her fingers into her lips and rubbed up and down in a petting motion. Then, feeling the warm, glossy wetness slide and sink it's way down her lips and on to her plump white butt cheeks, she slid a finger into her vagina. And then two, wriggling them around, attempting to flick her special spot, the way Justin sometimes does.
Little did she know that Justin was just arriving home three days early from his yearly business trip. His out of state work was complete, and his boss (who she was sure had the hots for her boyfriend) sent him home for a long deserved break. He decided he would not share this with Natalie, wanting to surprise her.
He pulled into the empty drive-way and leaped out of the car, unsuccessfully attempting to suppress the widening grin spreading itself over his face. Excitedly, he slid his key into the front door, cracked it open, and listened for Natalie- Nothing. He crept his way up the stairs and peeked into his empty bedroom. The sun shown brightly through the open window. He listened again, thinking that perhaps she was in the bathroom. Then, hearing slight hushed whimpers from outside, he crept to the window and glanced down at his yard. The sight floored him.
His young girlfriend lay, quite naked and sun kissed on the grass, pleasuring herself quietly. Instantly, he felt his dick thickening in his pants. He gasped, shocked at this highly erotic sight. He was so turned on, feeling naughty at his shameless act of voyeurism. He whipped out his member, stroking it at the sight of Natalie stroking herself. He quickly undressed himself and bolted down the two flights of stairs, nearly tripping himself on the final step. He crossed the bottom floor silently, like a thief, and peered out the screen door. Fully erect now, and throbbing hard, he determined what had to be done...
Suddenly, she heard the screen door open. She quickly grasped at the towel underneath for cover and averted her eyes, afraid and intensely embarrassed that she had been caught by this intruder. Her face turned a deep crimson and her heart was beating out her chest. Who was watching her? And for how long?
Justin entered the yard, crossing without a single word. Natalie peered up at him from beneath her towel shield, the look of relief washing over her face. And then she realized that he was naked too, and his cock was stiffer than she has ever seen it. He must have been watching.
"When did you get here?!," she asked, shocked that he was home (and that he was naked and hard). He did not answer. He said nothing. Justin lowered himself onto the grass, pressing his masculine body down on top of hers, he gazed into her eyes-a deep, penetrating gaze. She felt herself melt and a new, much more intense hunger overcame her. She immediately felt herself pining for him, throbbing for him. If he did not enter her now, she would surely crumble in agony.
